Some common PACKET frequencies:
NASA STS Orbiters and USSR MIR transmit on:
and may also listen on various frequencies for which an auxiliary offset can
be programmed on your FX-146.
National Simplex frequency:
RAMSEY FX-series Programming Worksheet
To convert N from decimal to binary, simply TRY to subtract EACH of the 16
binary values from N, always in descending order, always starting with
32768 and always ending with 1. This process will always yield 16 YES or
NO answers, which will give you exact diode installation instructions.

?
H41. Form one diode matrix "bridge" for the RECV row of holes. Using
the heavier gauge bare wire in your kit, shape, insert and solder this wire
bridge as illustrated.
?
H42a. Select seven (7) diodes from the master supply of 1N914 or
1N4148 switching diodes provided with this transceiver kit.
?
H42b. Set the PC board across two small boxes, blocks, cups or any
objects which provide a couple inches of clearance between the bottom
(solder side) and your work surface.
?
H42c. Stand the CATHODE (dark band) ends of the seven diodes down
into these positions (only) on the RECV row of the smaller matrix:
[ ] 8 [ ] 64 [ ] 256 [ ] 512 [ ] 1K [ ] 2K [ ] 8K+
?
H42d. Join, solder and trim the 7 RECV diodes so that all seven anode
wires are neatly connected to the RECV bus wire "bridge" installed in
Step H41.
?
H42e. Solder all 7 RECV line diode cathodes on the solder-side of the
PC board. Trim excess wires.
We have reached the mountain-top in building the RECEIVE section of your
transceiver as well as many sections or stages needed for transceiving.
Double-check your work as needed.
